COCK AND TANK FOR DRAWING FLUIDS OF VARYING TEMPERATURES.

SPECIFICATION forming part of Letters Patent No. 292,094,

dated January 15, 1884.

Application filed January 22, 1883. (No model.)

T0 at whom it may concern:

Be it known that I, JOHN BYRNE, a citizen of the United States, residingat Cleveland, in the county of Cuyahoga and State of Ohio, have inventedcertain new and useful Improvements in Cocks and Tanks for DrawingFluids of Varying Temperatures, of which the following is a description.

This invention relates to a class of devicessuch as coffee-urns ordispensing-fountainsprovided with faucets for drawing out the contents;and it has for its object to provide means for holding two fluidssuch ascoffee and waterin separate compartments of the same urn, and means fordrawing the two fluids to mix in such proportions in the act of runningas will produce a single fluid mixture of a given temperature.

To this end my invention consists in an urn or tank divided into twocompartments, and a faucet having a single outlet connected with bothcompartments, and in means for regu lating and gaging the flow of fluidfrom one compartmentwhile it is mixing with the fluid from the othercompartment, as hereinafter described and claimed, reference being hadto the accompanying drawings, in which- Figure 1 is a vertical section,part in elevation, of a dispensing-fountain according to my invention;and Fig. 2 is a side elevation of the same.

This invention is based on the hypothesis that two fluids of differenttemperatures will, when mixed, assume a mean temperature between the twohaving a fixed ratio with, if not directly proportional to, thequantities of the difierent fluids mixed, and that a fluid willdischarge from two different orifices in the same tank in quantitiesproportional to the areas of the said orifices. In accordance with theseprinciples I provide a fountain, A, with an annular partition, I),dividing the fountain into two compartments, A and B. IVith thesecompartments I connect a faucet having a single outlet, F, and twoinlets, a and 0. These inlets to the faucet are outlets to thecompartments A and B, respectively.

D represents a cock having two apertures on one side, registeringwiththe two passages a and a when suitably turned. It also has an apertureregistering with the outlet F at the same time, and its two apertures onone side connect through its center with the one aperture 011 the otherside, so that whenever the cock is turned to register with passages aand c the flow therefrom. will be discharged through the single outletF.

To graduate the proportion of discharge from the two passages, I providewithin the cock D a stopper, E, reduced in size along its centralportion, and shaped with opposite spiral shoulders c and e. The conicalsurface of this stopper is shaped to fit the interior of the cock, andthe relation of the shoulders e and e to each other and to passages cand a is such that when shoulder e nearly stops the passage a theshoulder e will leave passage 0 nearly wide open, and Vice versa. Thetwo extremes being connected by spirals, a gradation is produced whichgives all pos sible changes. To indicate the ratio between theseopenings, I provide a graduated scale on the cock D, to be read relativeto a line on the stopper E. The cock is provided with a handle, E, bywhich it may be turned, and the head of the stopper maybe milled orroughened, to be more easily held in turning it. Suppose the compartmentB to be supplied with water kept boilingthat is, at 212 Fahrenheitandthe compartment A to be supplied with coffee at 112 Fahrenheit. Now, bynoting the temperature of the mix ture drawn with the stopper at 'thevarious markings of the scale, said scale may be marked to degrees ofheat corresponding thereto and afterward set accordingly.

Other fluids may be drawn in the same manner, and the scale may bemarked to indicate the quantitative proportion of the mixture, insteadof its degree of heat.

hat I claim as my invention, and wish to secure by Letters Patent, is

1. The combination, with a faucet-body hav ing one outlet and two inletpassages, and a tubular stop-cock constructed to connect or to stop allof said passages, of a stopper fitted within said stop-cock, saidstopper having a reduced body and oppositely-inclined spiral shouldersat the ends of said reduced body, substantially as and for the purposespecified.
